Christina received an MSci in Physics from the University of Bristol in 2020 and completed a Master's thesis entitled: "Characterisation of Cryogenic Amplifiers for Single Photon Detectors". Following this, she developed an interest in silicon photonics which led her to join the Connected Electronic and Photonic Systems Centre for Doctoral Training (CDT) jointly run by University College London (UCL) and University of Cambridge. In 2021, she completed an MRes as part of this CDT and is now working towards a PhD in quantum dot laser integration on silicon with the ultra-fast photonics group at UCL.

Christina also enjoys participating in outreach-related activities. She has visited primary schools and sixth form colleges to spark interest for young people, and promote widening participation, within STEM subjects.

Research Summary

Christina's PhD is focused on integrating quantum dot lasers monolithically with a high-speed modulator to realise a novel transmitter for the silicon platform. Her research will involve modelling, developing and testing a modulator which will be compatible with the quantum dot laser-on-silicon technology pioneered by the photonics group at UCL. This project aims to merge the advantages of photonics for telecom and datacom solutions with the scalability and robustness of silicon.

This research is also in affiliation with the EPSRC project, QUantum Dots On Silicon (QUDOS) systems for communications, information processing and sensing.
